The Allen-Bradley 20F11NC037JA0NNNNN is a PowerFlex 753 AC variable frequency drive from Rockwell Automation. It is rated for 400V 3-phase input with 37 A continuous output current, delivering 18.5 kW normal duty / 15 kW (20 HP) heavy duty. The drive features an internal dynamic braking transistor, built-in EMC filter with common mode jumper, and integrated I/O (3 DI, 2 DO, 1 AI, 1 AO, 1 RS-485). Frame 3 open-type enclosure (IP20/IP00) with forced air cooling measures approximately 454×190×212 mm and weighs ~22.68 kg. The blank HIM configuration (no keypad) keeps cost down for networked applications. Output frequency up to 590 Hz. Typical applications include pumps, fans, conveyors, mixers, and general industrial motor control as part of Rockwell's Integrated Architecture.
Q: What is the difference between PowerFlex 753 and 755?
The 753 is a general-purpose drive with standard control, while the 755 offers higher performance, integrated safety options, and expanded I/O. The 753 is cost-optimized for standard applications.
Q: Does the 20F11NC037JA0NNNNN come with a keypad?
No, the "0" in the catalog number indicates a blank HIM (no keypad). A keypad can be purchased separately.
Q: What is the heavy-duty power rating?
15 kW (20 HP) in heavy duty mode, or 18.5 kW in normal duty.
